This application claims the benefit of U.S. Provisional Application No. 60/942,469, filed Jun. 7, 2007, and U.S. Provisional Application No. 60/942,467, filed Jun. 7, 2007. The disclosures of the provisional applications are incorporated herein by reference.

II. FIELD

The present disclosure relates in general to the field of concealed object detection, and in particular to a structural system for optimizing performance of a millimeter wave concealed object detection system.

III. DESCRIPTION OF RELATED ART

Security systems can be found at airports, train stations, arenas, construction sites, and other public, private, commercial and industrial facilities. In addition, security systems are used in field military operations to secure boundaries. One of the principal concerns of operators of security systems is the need to protect security personnel and innocent bystanders in the course of conducting a search of a person for concealed objects. The concealed objects that present a danger are weapons, explosives, contraband and other similar items that may endanger security personnel and other individuals in the proximity.

Typical metal or chemical residue detectors require security personnel to be in the proximity of the individual. For example, one or more security personnel are required to conduct a hands-on or “wand-based” scan of an individual for whom the metal or chemical residue detector has generated an alarm. An inherent deficiency of this type of security system is the fact that it exposes not only the security personnel to danger, but also other individuals in the vicinity of the security system to the dangers posed by such concealed objects. Passive millimeter wave concealed object detection systems have been developed that allow for a buffer zone between the individual and innocent bystanders. However, there is still a concern that when a concealed object is detected on a person, that the person may attempt to escape the area or injure others in the proximity using an explosive device (i.e., suicide bomber). Accordingly, there is a need in the relevant art for a structural system for optimizing performance of a millimeter wave concealed object detection system and that has the ability to protect security personnel and innocent by-standers from any potential threat or danger from a concealed object.

Another need exists in the art for a structural system for optimizing performance of a millimeter wave concealed object detection system having an environmentally-engineered internal configuration and construction allowing for a highly controlled inspection environment.

Another need exists in the art for a structural system for optimizing performance of a millimeter wave concealed object detection system that is suitable for imaging systems utilizing various forms of energy including millimeter waves, radio waves, visible light, infrared, ultraviolet, microwave energy.

Another need exists in the art for a structural system for optimizing performance of a millimeter wave concealed object detection system that increases the number of individuals that are screened.

Another need exists in the art for a structural system for optimizing performance of a millimeter wave concealed object detection system having maximum separation of screened persons and unscreened persons as well as the ability to closely deploy multiple millimeter wave concealed object detection systems in a side-by-side fashion.

Another need exists in the art for a structural system for optimizing performance of a millimeter wave concealed object detection system having a single concealed object detection system checkpoint lane, or multiple lanes.

Another need exists in the art for a structural system for optimizing performance of a millimeter wave concealed object detection system that includes complementary security technology or products including metal detectors, pan-tilt-zoom cameras, x-ray machines, radiological sensors, biometric sensors, iris scanners, palm scanners, finger print scanners, ID readers, etc.

However, in view of the prior art at the time the present invention was made, it was not obvious to those of ordinary skill in the pertinent art how the identified needs could be fulfilled.

 VI. DETAILED DESCRIPTION

A structural system for optimizing performance of a millimeter wave concealed object detection system is disclosed. The system provides effective control of the structural system surroundings and provides a known and successful environment in which the millimeter wave equipment can operate. Several components, techniques, technologies and methodologies including external millimeter wave energy mitigation, peripheral motion or clutter mitigation, test subject isolation, motion and flow control, threat containment, weather protection, decorative presentation, blast mitigation, and others may each be used separately, or in combination, with the system. In addition, the system includes multiple implementations and realizations.

Referring to FIG. 1, a particular illustrative first embodiment of a structural system for optimizing performance of a millimeter wave concealed object detection system is disclosed. The structural system takes the form of a separate free-standing structure containing a controlled entry point, a concealed object detection system, and a controlled exit point that is directly attached to (or in close proximity to) an entry or exit point to the parent structure. The parent structure may be an airport terminal or office building, for example. The structural system includes a foundation 102, external shell 104, an entry barrier 106 located at one end of the structure 100, and an exit barrier 108 located at the opposite end of the structure 100. The entry barrier 106 and exit barrier 108 control entry and exit from the structure 100 and may be equipped with magnetic or other automatic locking devices, doors, gate, turnstiles or the like, or may be manually opened. Permission to enter and leave the structure 100 is controlled by electric signs, buzzers, intercoms, or guard personnel positioned on, near, or by entry barrier 106 and exit barrier 108 as may be convenient or as required by the application. In some embodiments, control of the entry and/or exit barriers may be performed via the concealed object detection system and/or Programmable Logic Controller (PLC) for autonomous control. The shell 104 is designed to provide protection from the weather to ensure correct operating temperatures for the millimeter wave concealed object detection system and other installed equipment. The shell 104 optimizes performance of the millimeter wave concealed object detection system by eliminating or mitigating spurious millimeter wave emissions from outside or inside the structure 100. In addition, the shell 104 may be designed with blast and/or weapon resistant features including blast hatches, external vents, blast proof or resistant materials, and other damage mitigation features. The structure 100 may be equipped with air conditioning and heating arrangements appropriate to the geographical location which will maintain an interior operating environment conducive to proper operation of the detection system 116, and the comfort of operating personnel and subjects.

The interior of structure 100 is provided with an entry control point equipped with a turnstile 110 or other devices including gates, fixed railings, and stanchions to control entry and direct subjects where required as shown in FIG. 2. The floor 112 may be constructed with materials that optimize performance of the millimeter wave concealed object detection system 116 by eliminating or mitigating spurious millimeter wave emissions and/or reflections from outside or inside the structure 100. A fixed or portable X-ray luggage scanner 114 or similar device for screening luggage and personal effects may be located adjacent/or within the millimeter wave concealed object detection system 116. The millimeter wave concealed object detection system 116 consists of one or more detectors or cameras 118 positioned so as to detect concealed explosives, weapons, contraband, objects or prohibited objects. The millimeter wave concealed object detection system 116 may be equipped with a surrounding wall or barrier structure 120 consisting of portable or permanently installed materials to optimize performance of the detection system 116 or control entry and exit to the detection system. The surrounding wall or barrier structure 120, if utilized, may be designed to mitigate the effects of blast or weapons. If a surrounding wall or barrier structure 120 is not installed, a turnstile or other devices including gates, fixed railings, and portable stanchions may be utilized to separate and define the millimeter wave concealed object detection system 116. The millimeter wave concealed object detection system 116 is provided with an entrance or entrances 122 used to control access to the detection system 116. The entrances may be equipped with a turnstile, gates, door, drapes, cloth, stanchion or other devices used to control entry to the detection system 116. The interior of the detection system 116 is provided with an inspection lane 124 designed with materials that can optimize performance of the millimeter wave concealed object detection system 116 by eliminating or mitigating spurious millimeter wave emissions from outside or inside structure 100. The inspection lane 124 may be equipped with various types of wall or ceiling mounted signage and/or floor arrows to assist subjects during the scanning process. An exit or exits 126 is or are provided at the end of the inspection lane 124 to allow subjects to leave the detection system 116.

Referring now to FIG. 3, in operation the subject enters structure 100 through controlled access barrier 106. Upon entry, the subject passes through an optional turnstile 110 or an optional inner barrier or entrance vestibule. The subject is directed to the detection area by a guard and/or signage. The subject places his or her luggage and/or personal items in the X-ray scanner 114 to be scanned for explosives, weapons, or prohibited objects. The subject may be asked to remove his or her shoes and place them in the X-ray scanner or in or on an optional shoe scanner. When directed by a guard, signage, intercom, or buzzer the subject enters the millimeter wave concealed object detection system 116 via the entry 122. In a two camera system, the subject turns 90 degrees to enter the inspection lane 124. The subject traverses the inspection lane 124 at normal walking speed. The subject's back is scanned as he or she walks away from camera 118. The subject's front is scanned as he or she walks towards the camera 130. If the detection system 116 detects a possible explosive, weapon, or prohibited object, action is taken in accordance with local security procedures. If not, the subject exits the inspection lane 124 and picks up his or her personal effects at the X-ray scanner exit 128. The subject follows direction by a guard, signage, intercom, or buzzer and exits structure 100 via exit barrier 108.

For single weapons/object detection camera the structural systems, the subject may be commanded to stop and turn in front of the weapons/object camera and turn before continuing. In all cases, subjects may be commanded to raise their arms overhead to permit scanning and detection for concealed objects secreted under their arms.

The parent structure (e.g., airport terminal or office building) benefits from concealed object detection, and perhaps other security measures, conducted in a controlled, secured location directly outside of the parent structure, without requiring the structure to be placed at risk, modified, expanded or otherwise affected to incorporate the required security changes, equipment and logistics internally.

When used as an entry portal to a parent structure, upon successfully exiting the detection system, the subject is then mandated via the design of the structural system or via external components such as walls, fences, barricades, etc. to enter the parent structure. When used as an exit portal to a parent structure, the subject is mandated via the design of the structural system or via external components to exit the parent structure and enter the detection system.

Referring now to FIG. 4, a particular illustrative second embodiment of the structural system for optimizing performance of a millimeter wave concealed object detection system is disclosed.
